Active clinical trials for "Language Disorders"

The purpose of this investigation is to further develop and test a treatment for word-finding problems in aphasia. The treatment is designed to strengthen meaning associations within categories of words (e.g., animals, tools, fruits). The treatment is also designed to be used as a search strategy in instances of word-finding difficulty. The study was devised to evaluate the extent to which treatment increases the ability to recall trained, as well as untrained, words.

Brief Summary: Nearly 7% of elementary school children present with difficulties learning and using language. Unfortunately, language impairments are often long lasting and may have serious social, academic, and vocational ramifications. More than 1 million children receive language intervention in the public schools each year, and many more are seen in hospitals and other clinical settings. This randomized clinical trial compares the language outcomes of Fast ForWord to two other interventions (computer assisted language intervention without acoustically modified speech and individual language intervention) and to the outcomes of an academic enrichment (control) condition. Each year for 3 years, children will be randomly assigned to each of the four conditions at three regional sites (Austin, Texas, Dallas, Texas, and Lawrence, Kansas). The treatments will be administered in special summer programs. The primary research question is which intervention results in the most improvement in the composite language score from the Oral and Written Language Scales. Secondary questions include which intervention results in the greatest gains in conversational language,which intervention results in the greatest gains 3 and 6 months after training, which intervention results in the greatest improvement in auditory perception, and which intervention is the most cost effective. The results of the study will have theoretical and practical value. Theoretically, the study tests the temporal processing hypothesis of language impairment. Practically, the study will describe and compare the language, communication, auditory processing and academic outcomes of different language interventions. The study will help clinicians and administrators choose the most effective and least expensive treatment for the children they serve.

The use of non-invasive brain stimulation techniques like transcranial direct-current stimulation (tDCS) for rehabilitation of language is a growing field that needs further studies to determine how best it can be used to enhance treatment outcomes. It has been shown that tDCS can improve language performance in healthy and brain-injured individuals such as increased naming accuracy. However, at present, it is not known what effect tDCS has on higher-level language skills like discourse production (i.e. story telling, giving instructions) in healthy, older speakers. Therefore, the aim of this study is to investigate in healthy older adults, the effect of tDCS on discourse production as well as the ideal tDCS electrode placement for improving language at the discourse level. It is hypothesised that tDCS will result in greater language changes and improvements during discourse production compared to no stimulation.

The goal of this proposal is to examine the efficacy of a manualized treatment intervention, AMALS: Addressing Multiple Aspects of Language Simultaneously, which is designed to remediate semantic, morphological, and syntactic aspects of language in preschool children with language impairment. This study will target preschool children with language impairment living in a region characterized by nonmainstream dialects. Questions driving this work are: Will children participating in the AMALS treatment exhibit greater semantic, morphological, and syntactic complexity on multiple outcome measures at the completion of the intervention compared to a Discrete Trial Approach (DTA) group? Will these gains be maintained at one-month follow up? What is the impact of dialect on dependent variables, specifically morphosyntactic abilities? To answer these questions a randomized clinical trial will be conducted comparing AMALS, an integrated approach to treatment, with DTA, an additive approach to therapy. In this study rather than restrict the ethnic and cultural backgrounds of this population, children's use of dialect will be uniquely identified and examined.

The high incidence of neurodevelopmental disorders, including specific language and learning disorders, and their profund impact on the schooling of the children concerned remains a major public health concern. Early identification and intervention are a valuable tool for improving these problems. The developmental trajectory of children could be improved by knowledge enhancement, identification and strategies to support the teachers through the involvement of health professionals in the classroom

Children with Down syndrome (DS) have greater difficulty acquiring expressive language than is predicted by their general cognitive abilities and language comprehension (Miller, 1999). To date, interventions to improve communication outcomes for children with DS have met with only modest success. The proposed study is a randomized controlled trial of an early communication intervention combining two evidence-based treatments that teach expressive communication (Enhanced Milieu Teaching; EMT) and joint attention/symbolic play (Joint Attention Symbolic Play Engagement and Regulation; JASPER) using a dual mode (words +AAC). The intervention (a) teaches the foundations of communication (joint attention, play), (b) builds on positive child characteristics of social attention, (c) uses naturalistic strategies to increase the rate and complexity of communication and increase task engagement, (d) addresses the potential value of adding visual support (AAC) to spoken communication, and (e) includes parents as implementers of the intervention to promote generalization across settings and activities, and to ensure maintenance over time. It is hypothesized that children with DS enrolled in the intervention will have better language and communication skills at the end of treatment and followup than children in the BAU comparison group.The study will enroll 82 30 to 54 month old children with DS who have fewer than 20 words. Examining predictors of response to treatment and the effects of treatment on executive functioning will inform both theory and practice.

This research attempts to adapt and optimize a word learning treatment, specifically interactive book reading, for use with Kindergarten children with Specific Language Impairment (SLI). Children with SLI have difficulty learning language without any obvious cause for this difficulty. This study will examine the best way to achieve the appropriate intensity of 36 exposures. For example, is it better to hear the new words many times within the book (high dose) and to read the book few times (low dose frequency), or is it better to hear the new words a few times within the book (low dose) and to read the book many times (high dose frequency). The investigators hypothesize that reading the books many times will be more effective than repeating the words many times within a book.

The purpose of this study is to evaluate the effects of Response Elaboration Training (RET), which is a speech/language therapy for aphasia. The study is designed to determine whether verbal language production improves in terms of content and length of utterances as a result of treatment.

Up to 40% of stroke survivors suffer from aphasia, making recovery of language abilities a top priority in stroke rehabilitation. Conventional speech and language therapy may have limited effectiveness. Leveraging multimodal data (behavioral, neuroimaging, and genetics), this study aims to 1) evaluate the efficacy of combining tDCS with speech therapy, 2) examine neural changes associated with recovery, 3) identify factors influencing response to treatment.

The goal of the study is to examine the effects of teaching parents to use language support strategies on language skills in toddlers with language delays. We hypothesize that children whose parents who learn to use language support strategies at home will have greater language skills than those children whose parents do not learn the strategies.
